BURNER FOR GAS-RANGES.

Specification of Letters Patent,

Patented June 12, 1906.

Application liled MayS, 1905. Serial No. 258,712.

To all whom t may concern:

Be 1t known that I, CHARLES ENNIVS, a citi-l Zen of the United States, and a resident of i Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Burners for Gas-Ranges, of which the followin connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

In most gas-ranges two burner-tubes are employed for heating the oven, and in all gas-ranges of this class with which I am i`a. miliar each burneretube is controlled by a separate valve, so that the gas may be ade mitted to either or both of the tubes as de-4 sired. One objection to this arrangement is that when the valve to either burner-tube is closed the flame issues from the other burner? tube only and the heat is applied to one side of the oven. I have improved this con7 struction by providing each of the two burner-tubes with a longitudinal partition which divides each tube into two compartments and by roviding a plurality of burner-openings leading to each compart-y ment of each tube and by further providing means whereby the gas may be admitted to one or both compartments of each tube as desired.

In a burner embodying my invention whenever gas is admitted to both compartments of each burner-tube the maximum amount of heat is developed, but if it is shut off from one compartment of each burnertube a less degree of heat is produced, but said heat is evenly distributed over the bot` tom of the oven.

I preferably will make the burner-openings leading to one compartment of each tube larger than those leading to the other compartment, and by using either set of burner-openings or both sets various degrees can be secured.

Figure 1 is a vertical section through a portion of a gas-range', showing my burner applied thereto. Fig. 2 is a section on the line x, Fig. 1. Fig. 3 is a section on the line y y, Fig. 1. Fig. 4 is a top plan view of a portion of one burner-tube.

3 designates the upper oven of an ordinary gas-range, 4 the bottom of the oven, `and 5 thek lower oven, within which the ovenburners are located. These parts are or may r be of any suitable or usual construction.

My improved burner com rises two burnertubes 6 and 7, which preferalhly are connected by a cross-piece 8. Each burnertube has extending longitudinally thereofa partition I 9, which divides it into two compartments 10 and 11. The crossfpiece connection 8 is also divided into two compartments or passages 12 and 13 by a suitable partition 14, the passage 12 connecting the two compartments 11 .and the passage 13 connecting the two compartments 10.

15 designates burner-openings leading into the compartments 10, and 16 other burneropenings leading into the compartments 11.

It will be seen fromthe above description and from the drawings that the connected compartments 10 are entirely separate from the connected compartments 11, and therefore that gas admitted to either of the compartments 11 cannot pass into the compeut` ments 10, and vice versa.

I have provided means for admitting gas to either or both compartments of each burner-tube, so that either or both sets of burner-openings 15 and 16 may be employed, as desired. The means I have herein shown for accomplishing this purpose coinprises a valve 17 in la pipe ,or conduit 18, eading into the passageeway 1,3, and another independent valve 19 in a pipe or conduit 20, leading into the passagefway 1 2: Each of said pipes 18 and 20 is connected to a suitable source of gas-supply.

By opening the valve 17 gas will be admitted to the compartments 10 of the burnertubes, and similarly by opening the valve 19 gas will be admitted to the compartments 11 of said burner-tubes.

Preferably one set of burner-openings will be larger than those of the other, so that a larger or smaller iiame may be produced, depending on which set of burner-openings is used.

In the drawings I have illustrated the burner-openings 16 as being larger than the burner-openings 15.

When the maximum heating capacity of the burner is required, the gas may be admitted to both compartments of each burnertube. When a moderate heat is required, the valve 17 will be closed to shut off the gas IOO may be regulated without cutting down the pressure of the gas by partially closing the controllingfvalve, as is usually done in gasranges with which l am now familiar.

It will be seen that in my improved construction the size of the 'flame is determined by the size oi the burner-openings and the number of burner-op enings which` are brought into play, and not by cutting down the gaspressure by partially closing the valves.

ln using my improved burner l propose to have the valves 17 and 19 either entirely closed or entirely open.

The main feature of my invention is a burner-tube divided into two compartments with separate means for controlling the supply of gas to each compartment.

While l have herein shown one embodiment of my invention, l do not wish to be limited thereto, as the shape and. arrangement of the parts may be varied in many ways without departing from the invention.

Having fully described my invention, what l claim as new, and desire to secure by Letters Patent, is

1. ln a burner, two parallel burner-tubes, each divided longitudinally into two separate compartments, one compartment of each burner-tube being connected to the corresponding compartment of the other burnertube, each burner-tube having two parallel rows of burner-openings, the openings of one row communicating with one compartment and those of the other row communicating with the other compartment, the burneropenings which communicate with one pair of connected compartments being larger than those communicating with the other pair of connected compartments, and two independent valves to supply gas to the two compartments of each tube respectively.

2. In a burner, two parallel burner-tubes, each divided longitudinally into two comartments, a head or cross piece connecting the burner-tubes and also divided into two compartments which connect with the two compartments of each of the tubes, each burner-tube having two parallel rows of burner-openings, the openings of one row leading into one'compartment and those of the other to the other compartment, and the openings of one row of each burner-tube be-4 ing larger than those oi' the other, and a valve-supply connection leading to each compartment of the cross-piece.

3. ln a burner, a burner-tube divided by a longitudinal partition into two separate compartments, said tube having burner-openings leading to each compartment, the burner-openings leading to one compartment being larger than those leading to the other, and two independent valves to supply gas in dependently to each compartment.

4. In a'burner, two burner-tubes each divided by a longitudinal partition into two separate compartments, said tubes having burner-openings leading to each compartment, the burner-openings leading to one compartment being larger than those leading to the other, and two independent valves to supply gas independently to each compartment.

ln testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES ENNIS.
